SPECIFICATION forming part of Letters Patent No. 349,680, dated September 28, 1886,

lApplication led June 28, 1886.

To all whom it may concern:

Be it known that l, E. STILLMAN Blineoeii, a citizen of the United States, residing at Milton, in the county of Rock and State of Viscousin, have invented a new and useful Improvement in Vent-Hole Olosers for Pumps, of which the following is a specification.

My' invention is an improved vent hole closer for pumps 5 and it consists of the peculiar construction, combination, arrangement, and adaptation of parts, substantially as hereinafter described, and specifically pointed out in the claim. i

The object of my invention is to provide a device to be attached to the pump-pipe and be operated from the top of the well to open and close the vent ot' the pump, so as to allow the water to run out of the pump into the well and prevent it from freezing in the pump. A further object is the provision of means for this purpose which can be attached to any ordinary pump at a very small expense, which will be strong and durable and thoroughly efficient for the purposes intended. I attain these objects by the means illustrated in the accompanying drawings, in which- Figure l is a top plan view ot' my device secured 1n place upon .the pipe ot' a pump. Fig.

2 is a perspective view of my device detached from the pump. Fig. 8 is a longitudinal section on the line x x, Fig. l.

Referring by letter to the drawings, A designates a metal band adapted to pass around the pump pipe or cylinder, and provided on one side with a screw-threaded opening, in which opening works a set screw, B, which bears against the pipe or cylinder, and secures the band rigidly to the same. One of the free ends of this encircling band A is notched or cut out at a, and also provided with the lupwardly-extending arm or guide C. In the other free end oi' the band A is secured a screw, pin, or bolt, D, which projects outwardly from the said free end of the band, and forms a pivot for a cut-oft, E. A coiled spring, d, is placed on the pivot D, and bears against the cut-off E at one end, for the purpose presently described. rlhis cutoff E has secured to it at a suitable poin.J a rubber or leather block,`e, which is adapted to iit over the Vent-hole in SerialkNo. 206,499. (No model.)

the pipe and etfectually close the saine. The other end of this cut-off E tits or rests in the notch a, provided in the band A, and is also provided with an opening or eye, e', to enable a cord or wire or like means to be attached to the said cut-off to lift the same when desired. This cut-off also has depending from its under side about the center au ear or projection, e2, which forms a guard.

rIhe operation of my invention willbe readily understood 'rom the foregoing description, when taken in connection with the drawings.

The device is rigidly secured in place by means of the band and set screw, and the leather or rubber block orstopper is placed over the vent-hole by the cutoff, and the cord or wire which connects with lthe cut-o is passed up above the top of the well or cistern, so as to be in easy reach. Vhen it is desired to give vent to the pipes and prevent the water from freezing therein, it is only necessary to draw on the cord, which elevates the cut-oit', opening the hole in the pipe and allowing the water therein to run out and back into the well. rIhe guard provided on the cut-off appears in nfont ofthe opening, and prevents the water trom splashing and washing the sides of the well. I provide the spring inl connection with the cutoff, so that it' the pressure is too great on the cut-off the spring will give and release the rubber orleather stopper-from contact with the hole in the pipe.

It will be observed that I provide a device which can be secured to any pump employing a cylinder or pipe, and that the means provided for securing the same are thoroughly reliable, not likely to get out ot' order, and are cheap to manufacture.

Heretofore it has been the common practice to make a vent-openin g in the pump below the frost-line, and in the spring of the year the pump must be taken out of the well to cork up or close the vent-opening. My device overcomes this objection, as it can be operated from the top of the well by means of the connection to open and close the opening, and does away with the necessity of lifting the pump from the well to accomplish this purpose.

Having thus fully described my invention, I claim- IOO The herein-described attachment for pumps, i In testimony that I claim the foregoing` as comprising the attaching band A, open at my own I have hereto affixed my signature in Io one side, and provided with the clamp-screw presence of two witnesses.

B the out-off E arranoed across the open side Y I f of," the band and pivted at one end to the E' STILLMAB I PCOCI' hand7 a spring, d, bearing against the cut-off at the pivot-point, and a guard, e?, depending from the cut-off, for the purpose set forth.
